Effluent Decanter

The Vens effluent decanter removes treated water from the top of a tank evenly along its full width. A long slotted weir pipe, supported by end floats, follows the water level, and a pivoting pipe carries the flow to the outlet.
An actuator arm can raise the decanter clear of the water between decant cycles, which suits batch treatment processes.
